Implement all tasks given to you. Use a Fable high subagent to write a plan.md for each task. Require my approval for all plans before beginning implementation. Then write all code by calling out to codex exec for each task using codex --yolo exec -c model="gpt-5.5" -c model_reasoning_effort="high" < plan.md (allow cmd to run for up to 20 minutes), then review code (using a subagent with Fable high) and smoke testing new features (usage a subagent with Opus medium) by running pnpm dev and doing real requests, before committing and pushing, then moving onto next task. Remember that every subagent or codex session is completely independent and must be given the full context it needs to complete its work.

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

Here's a comparison of select(), poll(), and epoll(), focusing on their differences, advantages, and disadvantages.

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).
